⅓ cup water

1 (0.5-oz) pkg fresh basil

2 cups sliced peaches

½ cup fresh lemon juice

2 cups ice cubes

2 (12-oz) bottles sparkling water

Garnishes: lemon slices, fresh basil (optional)

 

Combine sugar, water, and basil in a small saucepan over medium heat, stirring until combined. Bring to a boil, reduce heat, and simmer 5 minutes. Remove from heat; cool to room temperature, about 30 minutes. Strain. Blend peaches and lemon juice in a blender until smooth. Fill a large cocktail shaker with ice.

Repeat process with remaining peach mixture and prepared syrup. Garnish, if desired.
